Which one of the following must be true about Freedom's schedule of voyages?

It seems as if both answer choices D and E could be correct

The most amount of trips you could take to Trinidad are 2 as well. Why is D a better answer choice than E?

@Eliaspite7, happy to help!

(E) is incorrect. It is possible to have more than two voyages to Trinidad. Careful not assume that it is impossible just because our past hypotheticals do not provide an example of it.

Here is a valid arrangement with three voyages to Trinidad:
T M T G J M T
1 2 3 4 5 6 7

Does that make sense? Hope it helps! Please let us know if you have any other questions!

Hi Eliaspite7, thanks for the question.

If you play around with the diagramming, you will actually find that there isn't a reason why we couldn't place T three times within the diagram.

For example: T M T G J M T

This abides by all of the rules, while placing T three times.

I hope this helps. Please let me know if you have any other questions.
